A New Mexico woman's engagement didn't work out, but instead of selling her diamond ring, she wanted to find a deserving couple to give it to. After posting the offer on Facebook, she received many stories, but one stood out.

Dozens of entries were submitted to the Inhabitants of Burque Facebook page, dedicated to Albuquerque stories. Josh Michaels told his tale of wedding woes last Monday and was chosen as the winner.

Engaged to Laura Aitken since 2013, Michaels was diagnosed with a rare form of stage four cancer. With so many medical bills, he has been unable to purchase a ring for Aitken, who has loyally stuck by his side through the ordeal.

By Tuesday, the anonymous ring donor was so touched by his narrative that she chose him as the recipient of the $2,100 diamond ring.

Thankful for the mystery benefactor's generosity, Micheals proposed again to his girlfriend, expressing his love while slipping the antique style sparkler on Aitken's finger.

The couple was also assured by its prior owner that the ring was filled with "positive vibes."
